Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed June 13, 1901. Serial No. 64,345.

lowing description, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.1

This invention is an improvement on the pegging-machine represented inapplication for United States Patent, Serial No. 672,507

filed ori the 4th day of March, 1898. That application shows a peg-stripcarrier or peg-- ribbon support operatively connected with the horn,stock-support, or work-support, whereby the position of the peg strip orribbon with relation to thepeg-forming means is changed according to thevarying thickness of the stock, so that there is formed a peg of aproper length to correspond with the stock being pegged. In thatapplication the rmeans shown for connecting the stock-support andthepeg-strip carrier or support was so constructed that the horn andpeg-strip carrier or support moved always substantially in unison.

In the machine herein shown the connecthe horn include a yieldingmediumin order that the horn may be given an eXtra depression when it isdesired to remove or apply the work without Veffecting a correspondingmovement of the strip carrier or sup ort. Preferably also stops areprovided to'limit the movement of the peg-ribbon support in bothdirections.

ANo. 490,624.

That a shortened peg may be cut from a I shown, a peg-strip guideway F,united by peg-ribbon, the peg varying in length aceordl screws orotherwise with a block F2 by an aning to the requirements of the stockbeing calipered between the foot-plate b4 and the upper end of the hornB, the following means have been provided.

I have mounted upon a stud k12 a lever hw, having at its upper end aroller-stud h, (shown by dotted lines, Fig. 1,) which is kept pressed bya spring g against the face of a cam g5, carried by the shaft C2, as inPatent No. 490,624. rlhe lower end of the lever hm actuates suitablemechanism, as provided for in my said application, to engage and movethe peg-strip F, represented as coiled and suitably sustained on a plate1", having a stud r2 entering a hole in an arm r3, iXed to the head A.

E2 indicates part of a driver-guide attached to the head B, as in UnitedStates Patent The guide has connected with it by a suitable screw 8 anose E, having usual holes for the awl and driver. The driver-passage inthe driver-guide is open at one side 10, as best represented in Figs. 6and 8, to leave a space or mouth through which the peg-forming meanspushes the formed peg into position under the driver, the peg beingdriven through the hole 12 in the nose and entering the stock resting onthe horn.

As shown in Figs. 6 and 8, the guide E2 receives against it one end of ablock E3, having an ear 13, which embraces a portion of the driver-guideE2. The block E3 is grooved, as illustrated in this present embodimentof my invention, to receive and guide the pegforming means and thesurplus -ren1over. The peg-forming means presents two operating cuttingedges, one designated 15X and the other 15W. The edge 15 occupies avertical position and coperates with the vertical wall 8O of the throat36 in the block E3, which communicates with the open side 10 of thedriver-passage. The peg-shortening edge 15 is substantially horizontaland cooperates with the top or upper edge 35 or" the throat 36 andserves with the edge 15X to form at one operation a shortened peg, suchas n, Fig. 9. The edges 15 and 15XX are represented as formed on one andthe same blade 15.

The surplus-remover 14 has its edge 14 located somewhat behind the edgeof the pegforming device, and it is shown as connected therewith in anadjustable manner by a bolt 16 in a slot 17. The edge oi' thesurplus-remover meets the peg-strip at its side opposite that whichcontacts with the wall 37 orn the block E3 above the throat 36, cutsinto the peg-strip, and removes any surplus wood, such as n', Fig. 9,left after the operation or' the peg-former. The line of the cut made bythe surplus-remover is indicated by the dotted line n2 in Fig. 9.

The plate r has connected with it, as

gle-iron F3. (See Figs. 5 and 8.) 'lhe block F2 and guideway Fconstitute one suitable form of peg-strip carrier or support.

Viewing Figs. 6 and S, it will be seen that the end or' the peg strip orribbon F occupies a position in the slot 3() of the block E when a pegis to be formed by the operation ol' the peg-forming means. The head ofthe peg will be formed at a distance from the upper edge of the stripequal to the distance between the upper edge of the strip and the upperhorizontal shoulder 35 of the throat 36.

The blade 15 has a slot 1S, which is entered by a pin or projection 19,(sec dotted lines, Fig. 1,) carried by an arm 20, common to saidapplication, mounted to turnlooscly on a stud 21, extended from thel'rame A, said arm 20 having a stud 22, (shown by dotted lines, Fig. 1,)which is embraced by a link 24, embracing a stud carried bythe movablehead B, so that said head in its feeding movement may turn the arm 2()and actuate the peg-forming means and surplus-remover at the propertimes a spring 68, common to said application, and having its coiledpart embracing a stud-screw 68X, one end of said spring acting againstsaid lever taking up lost motion in the peg-forming means.

The block E3 has a suitable groove, (sec Fig. 5,) which receives aprojection m, extended Yfrom the part F2 oi: the peg-strip earricr orsupport. The part F2 receives a stud or other screw F4, which isembraced by a link m', loosely connected with the front end of a leverm2, pivoted at mi* on a stand m, erected on a fixed part of the head A.The rear end oi said lever m2 has jointed to it a rod m, (see Figs. 1,2, and 3,) connected at its lower end with a block 60, surroundingloosely the rod d' The block 6() is engaged on its upper and lower sidesby springs 61 and 62, which surround rod d, and are engaged at theiropposite ends, respectively, by a nut 63 and a collar 64, the nut beingadjustable to change the tension of the springs. These springsconstitute one form of a yielding medium in the connections between thepeg-strip carrier and the horn.

The parts thus far described, with the exception of the block 60, thesprings 61 and 62, and the nut and collar 63 and 64, are common to myapplication bereinbefore referred to, and the present invention relatesparticularly to the yielding medium in the connections between thepeg-strip carrier and the horn. One object of this yielding connectionis to enable the peg-strip carrier to follow the horn in all changes ofposition occasioned by varying thickness of the stock, but prevent itfrom following the horn in theextreme movements of the horn, as when itis given an extra depression or when it rises to an unusual height. Itis unnecessary and undesirable IOO IIO

for the peg-strip carrier to follow these ex-V treme variations in theposition of the horn.

When the horn is given an extra depression for the removal orapplication of stock, a suitable stop 65, shown as a stud-screw extendedfrom the projection m of the peg-strip carrier, (see full lines, Figs. 1and 8, and dotted lines, Fig. 5,) meets the lower endof a slot 66, outin the block E3, and prevents further downward movement of the peg-stripcarrier. Thereafter in the further downward movement of the horn thespring 62 will yield and no further movement will be imparted to rod m3Xand through it to the peg-strip carrier.

When the stock is removed and the horn is released, the spring bsacts tolift the horn, and if the horn should rise to an unusual height, as incase no work were between it and the foot-plate', the stop 65 would meetthe upper end of the slot 66 and limit the extent of upward movement ofthe strip-carrier. It will thus be observed that the movement of thepeg-strip carrier is yieldingly eHected in both directions.

In the form in which I have herein chosen to illustrate my invention thepeg-forming means and peg-shortener are shown as slidably mounted inaguideway of the block E3, extended laterallyv from the nose having thedriver-passage, andthe supp ort for sustaining the peg-ribbon is placedin a slot between said block and nose and is made vertically movable insaid slot for-a greater or less distance through .connections betweenone end of the lever m2, which is jointed to the pegribbon support, andto a rod connected with the horn-lever, which latter is connected withthe horn-rod b3. When, therefore, the position of the horn is changeddue to` variationsin thickness of the stock interposed between the topof the horn and the under side of the nose, the peg-ribbon support willbe moved vertically more or less in said space, and more or less of theupper edge of the peg-ribbon will be put above the edge X according tothe length desired for the shortened peg next to be cut and driven. Thepeg-ribbon support having been put automatically in its proper positionfor a peg of the desired length, due to change of position of the hornin calipering the stock, the cutters 15' and 14 will be moved toward thepeg-ribbon, and blade 15 will cut out the shortened peg and force itthrough the throat 36 into the driver-passage of the nose, and duringthis operation the edge of blade 14 will meet the part of the peg-woodsustained by the face 37 above the shoulder and will cut off and removefrom the pegribbon the surplus, (designated by n, Fig. 9.)

The springs 61 and 62 are strong enough to resist any materialcompression as the horn is moved in usual manner to caliper the stock inwhich the peg is to be driven; but said springs may yield topermit thehorn to be' abnormally moved, as by or through pres- `sure of the -footof the operator on the horntreadle C". y

It will of course be obvious that the advantage of the present inventionwould be equally well secured if the peg-forming means were movable andthe peg-strip carrier stationary. The essential thing. is to have one ofthese parts movable with relation to the other and to have the movablepart yieldingly connected with the mechanism which is arranged tomeasure the thickness of the stock, and that mechanism is, in the formvin which my invention is herein shown, the horn or stock-suport.

I-Iaving described my invention, what I claim, and desire to secure byLetters Patent, is-
